So I've made the decision that when I move into a bigger house at the end of the year, I'm going to dedicate my whole fish room full-force to figuring out how to breed true blue dragon bettas. Not blue bodied, but real silver-bodied, blue finned dragons-
This image is fake, but it represents the goal. So far, no one has successfully been able to create these. I believe that starting the line with a blue cambodian crossed with a dragon with thick scaling and plenty of selective breeding might get me to my goal. Dragons came about by crossing betta splendens to wild type bettas, to try to cross over the genetics of the wild types that contain the heavy iridescence on their scales. Every dragon betta has a soft iridescent sheen across all of their scales, it's just more difficult to see on some than others. Original blue-bodied blue dragons have a lot more body iridescence on them, which is what causes the blue cast across the body. I believe that crossing a dragon with a blue cambodian will encourage the fleshy colored body, while at the same time causing blue fins and thick, light colored scales. This won't become apparent on the F1 generation as cambodian is recessive.
It will be difficult trying to find a blue cambodian as they are pretty rare, but if this project fails I plan on breeding blue cambodians anyways to make them more accessible in the betta community.
Any opinions or tips?
